Measurements were conducted in tissues collected on the 18th of August. Starch was expressed in glucose equivalents. Data show means (n = 5 ± SE). Different letters in rows indicate significant difference at P ≤ 0.05 (Tukey’s HSD test following ANOVA). +A = soil amendment; 0, 2, and 6 h indicate the time of air exposure of bare-rooted seedlings before planting
